Complete the table so that it does not represent a function of x. How do you know the new ordered pair would not make this a function?
Add a new pair (6, 20) This would not make it a function because the same x-value has two different y-values.
Add a new pair (7, 18). This would not make it a function because the y-value is repeated.
Add a new pair (6, 18). This would not make it a function because the x-value is repeated.
Add a new pair (8, 20). This would not make it a function because the x-value is different.
